To be honest, although Bush's and his cronies think science is a mute point since the bible reveals everything, the hubble is a little past its prime.

There's ground based technologies that our now matching or exceeding the capabilities of hubble and it's hard to ask for money to fix a big lense in the sky when you need 80 billion (more) to run a war in Iraq.

Sad to see such a nice tool of science go though. It took some pretty amazing pictures, even if they were digitally coloured by some lady working on a Mac.
